Want to shoot some cool underwater video in a difficult-to-reach location? You can either hire a submarine or just buy one.

Venerable gadget-meisters Hammacher Schlemmer are selling "The Submarine Camcorder," a remote-controlled mini sub with a built-in HD camcorder. The tiny, 19-pound submarine (9" L x 14 1/2" W x 7" H) sends a live video feed from its cockpit to an iPad from up to 100 feet underwater, letting you observe and record marine life.

"Communicating with the receiver using Wi-Fi, an app installed onto an iPad or laptop remotely controls the sub's electric thrust and lift propellers for forward/backward (5 kts forward; 1 kt reverse), left/right, and up/down movement. A virtual dashboard (an iPad's motion sensors can also steer the sub) includes a joystick, camera controls, and displays depth, heading, battery level, and temperature data received from the sub's built-in sensors. Its marine-grade, hydrodynamic ABS housing provides a watertight seal to protect the included HD video camera, which captures 1280 x 720 resolution footage (1280 x 800 for still images)."

Sounds pretty cool, right? Yes, but it sure ain't cheap, retailing for USD$6,300. If that's too rich for your blood, you might want to check out the much more affordable DiveBot, which is excepted to sell for around USD$1,170.
